BACKGROUND 1. Technical Field

The present disclosure relates to an escape system and an ultrasonic component thereof, in particular, to an escape system for a sinking car and an ultrasonic component thereof, which are helpful to fast receive information indicating the car has been fallen into the water and quickly send the information, so as to grasp a rescue opportunity.

2. Description of Related Art

Propaganda materials of governments teaches people that a car head easily fall downward due to a weight of an engine of the car head when the car driven by a user accidently falls into water, and under such condition, the user in the car should keep calm, unlock a locked seat belt in the first time, then open a car window as soon as possible, and climb out via the car window before the car has completely fallen into the water. If the car has fallen into the water, the car window is hard to be opened since the interior and exterior of the car window have a pressure deviation due to the water pressure, and the automatic car window also cannot be activated since the water has flowed into the electronic component of the car. Meanwhile, the car will complete fallen into the water in about 90 seconds, and the user must find a sharp object and use the sharp object to break up a front or back window to grasp the escape opportunity. If the user cannot grasp the escape opportunity in the short time period of 90 seconds, the rescue opportunity of the user is very little.

One technology is provided to solve the above problem. The self-rescue system comprises a car body, an inflating structure, a water level sensor and a control unit. The car body has a side on which the inflating structure is disposed, and the inflating structure comprises a high pressure gas bottle, a floating ball and a floating ball control module, wherein the high pressure gas bottle is disposed in the car body, the floating ball is disposed outside the car body, and the floating ball control module is connected to the high pressure gas bottle and the floating ball, and comprises a fixing ring, a switch activator for inflating the gas bottle and a driver. The water level sensor is disposed outside the car body, and the control unit is electrically connected to the water level sensor and the floating ball control module. Thus, when the water level sensor detects that the water level is too high, the inflating structure is activated to quickly inflate the floating ball of the inflating structure, such that it prevents the car body from falling into the water to rescue the life the user. Further, the top end of the headlight has a help light, and the help light can flash, such that the user can wait to be rescued. However, when the car falls into the water, the water level sensor and the floating ball is pulled upward due to the water floating force, but because of the tension force of the spring being the resisting force, the activating time of the inflating ball is affected and the signal transmitting time of the water level sensor is delayed. Thus, the inflation time of the inflating ball is delayed, and it decreases the rescue chance of the user in the car. Accordingly, how to utilize a novel design to efficiently help the car falling into the water to transmit the rescue signal quickly for grasping the rescue opportunity is an important issue which the researcher or manufacture in the field of the escape system for the sinking car tries to solve and overcome.

Therefore, a warning signal indicating that the car falls into the water can be fast sent, and this makes sure that the rescue opportunity which the car falls into the water can be grasped to decrease the damage or death of the user.

The drawings are for illustrative and auxiliary purposes only and may not necessarily be the true scale and precise configuration of the present disclosure. Therefore, the scope of the present disclosure should not be limited to the scale and configuration of the attached drawings.

Firstly, referring to FIG. 1A through FIG. 1C, an ultrasonic component (1) of the present disclosure at least comprises a case (11) and an ultrasonic module (12).

The case (11) has a housing (111) space therein, wherein at least one side of the case (11) has at least a perforation (112), and two sides of the perforation (112) have at least two masking pieces (113) being disposed corresponding to the two sides of the perforation (112), wherein the masking piece (113) and the side of the case (11) have an angle (θ) therebetween. The angle (θ) can be 5 degrees through 65 degrees, for example. In a preferred embodiment, the case (11) is a square case, and interior of the case is formed with the housing space (111), the housing space (111) is filled with air, and each of a left and right sides of the case (11) has the corresponding perforation (112), and each of a top and bottom sides of the perforation (112) has the corresponding masking piece (113). Preferably, the masking pieces (113) located on the top and bottom sides of the perforation (112) are parallel to each other, the side of the case (11) and one masking piece (113) of the corresponding perforation (112) therebetween have the angle (θ) being 5 degrees through 65 degrees, and the side of the case (11) and other one masking piece (113) of the corresponding perforation (112) therebetween have a complementary angle of the angle (θ). The angle (θ) between the masking piece (113) and the side of the case (11) can be used to prevent the water from splashing into the interior of the case when the user washes his/her car or it rains, and thus the false determination is avoided.

The ultrasonic module (12) is disposed in the housing space (111), and the ultrasonic module (12) comprises an ultrasonic signal transmitting unit (121), a receiving unit (122), a calculating unit (123) electrically connected to the receiving unit (122) and a signal transmitting unit (124) electrically connected to the calculating unit (123). Preferably, the receiving unit (122) is electrically connected to the ultrasonic signal transmitting unit (121), or alternatively, the calculating unit (123) is electrically connected to the ultrasonic signal transmitting unit (121). The ultrasonic signal transmitting unit (121) emits an ultrasonic (U) continuously or every period, the receiving unit (122) receives the ultrasonic (U), and preferably, the ultrasonic signal transmitting unit (121) transmits the speed, frequency and wavelength of the ultrasonic (U) to the receiving unit (122). The receiving unit (122) analyzes the speed of the ultrasonic (U) and converts it to a transmittance rate or a reflection rate, or alternatively, the receiving unit (122) analyzes a time deviation between a time which the ultrasonic signal transmitting unit (121) emits the ultrasonic (U) and a time which the receiving unit (122) receives the ultrasonic (U), or alternatively, the receiving unit (122) analyzes a reflection distance according to the time deviation.

To put it more concretely, after the ultrasonic (U) contacts an obstacle (O) (refer to FIG. 1B and FIG. 1C), the ultrasonic (U) transmits into the obstacle (O) to generate a transmittance wave (U1) and collides the obstacle (O) to generate a reflected wave (U2). In other words, the ultrasonic (U) has the transmittance wave (U1) and the reflected wave (U2). The receiving unit (122) analyzes the speed of the transmittance wave (U1) and converts it to the transmittance rate and the reflection rate of the obstacle (O), or alternatively, the receiving unit (122) analyzes the time deviation between the time which the ultrasonic signal transmitting unit (121) emits the ultrasonic (U) and the time which the receiving unit (122) receives the reflected wave (U2), or alternatively, the receiving unit (122) analyzes the reflection distance between the obstacle (O) and the ultrasonic module (12) according to the time deviation.

Next, the calculating unit (123) compares the transmittance rate send from the receiving unit (122) to a built-in transmittance rate set value, or alternatively, the calculating unit (123) compares the reflection rate sent from the receiving unit (122) to a built-in reflection rate set value, or alternatively, the calculating unit (123) compares the time deviation sent from the receiving unit (122) to a built-in time deviation set value, or alternatively, the calculating unit (123) compares the reflection distance sent from the receiving unit (122) to a built-in reflection distance set value. When the transmittance rate is different from the built-in transmittance rate set value, or when the reflection rate is different from the built-in reflection rate set value, or when the time deviation is different from the built-in time deviation set value, or when the reflection distance is different from the built-in reflection distance set value, the calculating unit (123) generates a warning signal which indicates the car has been fallen into water to the signal transmitting unit (124), and the signal transmitting unit (124) transmits the warning signal via a wired manner or a wireless manner. For example, when the transmittance rate is larger than the transmittance rate set value, or when the reflection rate is less than the reflection rate set value, or when the time deviation is less than the time deviation set value, or when the reflection distance is less than the reflection distance set value, the calculating unit (123) generates the warning signal to the signal transmitting unit (124), and the signal transmitting unit (124) the signal transmitting unit (124) transmits the warning signal via the wired manner or the wireless manner. Further, the ultrasonic signal transmitting unit (121) is one of an ultrasonic signal transmitting component or an ultrasonic signal transmitting device. In a preferred embodiment of the present disclosure, the ultrasonic signal transmitting unit (121) is the ultrasonic signal transmitting component which emits the ultrasonic (U), and the receiving unit (122) receives the ultrasonic (U) emitted by the ultrasonic signal transmitting unit (121) and analyzes the transmittance rate, the reflection rate, the time deviation and the reflection distance.

Referring to FIG. 1B simultaneously, the ultrasonic signal transmitting unit (121) and the receiving unit (122) are disposed on one side of the housing space (111), for example, the ultrasonic signal transmitting unit (121) and the receiving unit (122) are disposed on the top side of the housing space (111), and the ultrasonic signal transmitting unit (121) synchronously transmits a start time to the receiving unit (122) when emitting the ultrasonic (U). The ultrasonic signal transmitting unit (121) emits the ultrasonic (U) forward the bottom side of the housing space (111), and next, the ultrasonic (U) collides the obstacle (O) disposed on the bottom side of the housing space (111) to generate the reflected wave (U2). In the embodiment, the obstacle (O) is the water, and for example, the water flows to the housing space (111) via the perforation (112). The portion of the housing space (111) being not occupied by the water is filled with the air, and the receiving unit (122) receives the reflected wave (U2) and marks a receiving time. The receiving unit (122) subtracts the start time from the receiving time to obtain the time deviation, and the receiving unit (122) transmits the time deviation to the calculating unit (123). The calculating unit (123) has the built-in time deviation set value, and the calculating unit (123) calculates the difference between the time deviation and the built-in time deviation set value (or compares the time deviation to the built-in time deviation set value), when the time deviation and the built-in time deviation set value are different from each other, for example, the time deviation is less than the time deviation set value, the calculating unit (123) generates the warning signal to the signal transmitting unit (124), and next, the signal transmitting unit (124) transmits the warning signal via the wireless or wired manner. It is noted that, when the housing space (111) has no obstacle (O), the ultrasonic (U) directly collides the bottom side of the case (11) to generate the reflected wave (U2), and the measured time deviation now can be the time deviation set value.

In addition, the receiving unit (122) analyzes the time deviation to calculate the reflection distance between the obstacle (O) and the ultrasonic module (12), the reflection distance is a which the half time deviation multiplies the speed of the ultrasonic (U), or the reflection distance is a product which the time deviation multiplies the speed of the ultrasonic (U), or the reflection distance is a product which the half time deviation multiplies the speed of the reflected wave (U2), and the receiving unit (122) transmits the refection distance to the calculating unit (123). The calculating unit (123) has the built-in reflection distance set value, the calculating unit (123) calculates a difference between the reflection distance and the built-in reflection distance set value (or compared the reflection distance to the built-in reflection distance set value). When the reflection distance is different from the built-in reflection distance set value, for example, the reflection distance is less than the reflection rate set value, the calculating unit (123) generates the warning signal to the signal transmitting unit (124). Next, the signal transmitting unit (124) transmits the warning signal via the wireless or wired manner. It is noted that, when the housing space (111) has no obstacle (O), the ultrasonic (U) directly collides the bottom side of the case (11) to generate the reflected wave (U2), the measured time deviation now can be the time deviation set value, and the reflection distance set value is the product which the half time deviation set value multiplies the speed of the ultrasonic (U), or the reflection distance set value is the product which the half time deviation set value multiplies the speed of the reflected wave (U2).

Referring to FIG. 1C simultaneously, the ultrasonic signal transmitting unit (121) and the receiving unit (122) are disposed on two opposite sides of the housing space (111), for example, the ultrasonic signal transmitting unit (121) is disposed on the top side of the housing space (111), and the receiving unit (122) is disposed on the bottom side of the housing space (111). The ultrasonic signal transmitting unit (121) emits the ultrasonic (U) forward the bottom side of the housing space (111), and preferably, the ultrasonic signal transmitting unit (121) emits the ultrasonic (U) forward the receiving unit (122). Next, the ultrasonic transmits into the obstacle (O) disposed on the bottom side of the housing space (111) to generate the transmittance wave (U1), and in the embodiment, the obstacle (O) is the water which covers the receiving unit (122). For example, the water flows to the housing space (111) to cover the receiving unit (122) via the perforation (112). The portion of the housing space (111) being not occupied by the water is filled with the air, and the receiving unit (122) receives the transmittance wave (U1) to analyze the speed and the transmittance rate of the transmittance wave (U1). For example, when the receiving unit (122) analyzes that the speed of the transmittance wave (U1) is larger than the speed of the ultrasonic (U), the receiving unit (122) calculates the transmittance rate, and then the receiving unit (122) transmits the transmittance rate to the calculating unit (123). The calculating unit (123) has the built-in transmittance rate set value, preferably, the transmittance rate set value can be 0. The calculating unit (123) calculates a difference between the transmittance rate and the transmittance rate set value (or compares the transmittance rate to the transmittance rate set value), and when the transmittance rate is different from the transmittance rate set value, for example, the transmittance rate is larger than the transmittance rate set value, or when the transmittance rate is larger than, the calculating unit (123) generates the warning signal to the signal transmitting unit (124). Then, the signal transmitting unit (124) transmits the warning signal via the wireless or wired manner. It is noted that, an uncompressible rate of the water is 2.2×10⁹ (Pa), an uncompressible rate of the air is 1×10⁵ (Pa) being less than that of the water, and the speed of the ultrasonic increases as the uncompressible rate of the material increases. Therefore, when the car falls into the water, and the water covers the receiving unit (122), the speed of the transmittance wave (U1) is larger than that of the ultrasonic (U).

The receiving unit (122) analyzes the transmittance rate by using an equation as follows:

${T = \frac{4\rho_{1}C_{1}\rho_{2}C_{2}}{\left( {{\rho_{1}C_{1}} + {\rho_{2}C_{2}}} \right)^{2}}};$ wherein T is the transmittance rate, ρ₁ is an air density, C₁ is the speed of the ultrasonic (U), ρ₂ is a water density, and C₂ is the speed of the transmittance wave (U1); ρ₁, ρ₂ and C₁ are independent and different constant values stored in the receiving unit, and C₂ is measured by the receiving unit (122). In the embodiment of FIG. 1C, the obstacle (O) is the water, and the portion of the housing space (111) being not occupied by the water is filled with the air. For example, under the following condition, ρ₁=0.0012 g/cm³, C₁=0.331×10⁵ cm/sec, ρ₂=1.00 g/cm³, and C₂=1.43×10⁵ cm/sec, the calculated transmittance rate T equals to 0.00117. In the embodiment that the transmittance rate set value is 0, the calculating unit (123) calculates a difference between the transmittance rate and the transmittance rate set value (or compares the transmittance rate to the transmittance rate set value), and when the transmittance rate (T=0.00117) is larger than the transmittance rate set value (0), the calculating unit (123) generates the warning signal to the signal transmitting unit (124). Then, the signal transmitting unit (124) transmits the warning signal via the wireless or wired manner.

The receiving unit (122) analyzes the reflection rate by an equation as follows:

${R = \frac{\left( {{\rho_{1}C_{1}} - {\rho_{2}C_{2}}} \right)^{2}}{\left( {{\rho_{1}C_{1}} + {\rho_{2}C_{2}}} \right)^{2}}};$ wherein R is the reflection rate, ρ₁ is an air density, C₁ is the speed of the ultrasonic (U), ρ₂ is a water density, and C₂ is the speed of the transmittance wave (U1); ρ₁, ρ₂ and C₁ are independent and different constant values stored in the receiving unit, and C₂ is measured by the receiving unit (122). In the embodiment of FIG. 1C, the obstacle (O) is the water, and the portion of the housing space (111) being not occupied by the water is filled with the air. For example, under the following condition, ρ₁=0.0012 g/cm³, C₁=0.331×10⁵ cm/sec, ρ₂=1.00 g/cm³, and C₂=1.43×10⁵ cm/sec, the calculated reflection rate T equals to 0.99883. In the embodiment that the reflection rate set value is 1, the calculating unit (123) calculates a difference between the reflection rate and the reflection rate set value (or compares the reflection rate to the reflection rate set value), and when the reflection rate (R=0.99883) is less than the reflection rate set value (1), the calculating unit (123) generates the warning signal to the signal transmitting unit (124). Then, the signal transmitting unit (124) transmits the warning signal via the wireless or wired manner.

The ultrasonic component (1) is especially applied to the car after the car falls into the water, by utilizing the properties of the ultrasonic (U) in two different mediums (such as, the water and air) are different from each other (i.e. the reflection rate, the transmittance rate, the time deviation and the reflection distance of the ultrasonic (U) are respectively different from the reflection rate set value, the transmittance rate set value, the time deviation set value and the reflection distance set value), whether the car falls into the water can be detected, which is helpful to fast send the information that the car has been fallen into the water and to grasp the rescue opportunity.

Further, the interior of the perforation (112) may further have a permeable layer (114), such as, a fiber material layer or a cloth layer.
